Enjoy seamless connectivity on this exclusive island with SouthESIM's St. Barts eSIM plans, starting at just $1.99. Choose from 7 limited and 14 unlimited plans.
CRITICAL WARNING: St. Barts is NOT in the EU Roaming Zone!
This is the most common (and expensive) mistake travelers make:
- Saint Barthélemy is a French Overseas Collectivity, but unlike Martinique or Guadeloupe, it is NOT part of the European Union (EU).
- This means your "Roam Like at Home" (EU roaming) plan DOES NOT APPLY HERE.
- Most carriers (from the US, UK, and Europe) classify St. Barts as a "Rest of World" zone, charging astronomical fees.
A St. Barts eSIM is the only smart way to get affordable data. Get connected the moment you land at Gustaf III Airport (SBH) or arrive by ferry.

Frequently Asked Questions
Most contemporary smartphones released in the past few years are designed to support eSIMs, making SouthESIM a convenient option for many travelers. This includes popular models like the iPhone XS and all newer versions, Google Pixel 3 and its subsequent models, and the Samsung Galaxy S20 series and later. Beyond phones, an increasing number of tablets, smartwatches, and even some laptops also feature eSIM capability. The quickest way to confirm if your specific device is ready for SouthESIM is to check its settings for an 'Add eSIM' or 'Add Data Plan' option.
Great news for travelers! Almost every flagship smartphone released since around 2019 is equipped with eSIM technology, making SouthESIM an incredibly convenient choice for international adventures. This includes widely used models such as the iPhone XS and all newer generations, the Google Pixel 3 and its successors, and the Samsung Galaxy S20 series and all subsequent models. Plus, a growing list of mid-range devices are also joining the eSIM club. If your phone has an option in its settings to 'Add eSIM' or 'Add Data Plan,' you're likely all set for SouthESIM!
No! This is the #1 roaming trap in the Caribbean. Although St. Barths is a French collectivity, it is NOT part of the European Union. Your EU/French "Roam Like at Home" plan does not apply. Most carriers (including Orange FR) will charge you extremely high international roaming fees, often the most expensive rates they have. A SouthESIM eSIM is the only way to get a fixed, prepaid data price and avoid a bill shock.
This specific plan is valid only for St. Barths. This is a critical point. 99% of visitors land at Sint Maarten (SXM) first and then take a ferry or small plane. Sint Maarten is a separate, dual-country territory. We strongly recommend our Caribbean Regional eSIM, which covers both Sint Maarten and St. Barths, to ensure you are connected from the moment you land.
To give you the best speed and coverage on the island, our eSIM connects to the premium local providers, typically Digicel or Dauphin Telecom (Orange Caraïbe). This ensures you get the fastest available 4G/LTE speeds, whether you are in the capital Gustavia, at Nikki Beach, or at your villa.
Yes, for mobility and security. While luxury villas and 5-star hotels (like Eden Rock or Cheval Blanc) have good Wi-Fi, it is fixed to the property. A personal eSIM gives you a private, secure connection that works everywhere, on St. Jean Beach, at Saline Beach, or when driving around the island. It is essential for using Google Maps on the island's steep, narrow roads.
Yes. The local networks (Digicel/Dauphin) have strong towers that provide excellent 4G/LTE coverage to the main harbors (Gustavia, Anse du Corossol) and the most popular coves and beaches (like St. Jean). You will be able to stay connected from your boat as long as you are close to shore.
Checking for eSIM compatibility is usually straightforward. Most smartphones from the last few years, especially models like iPhone XS and newer, Samsung Galaxy S20+ series, and Google Pixel 4 and up, are eSIM-ready. The quickest way to be sure is to check your phone's settings under 'Mobile Data' or 'Cellular Plan' for an option to 'Add eSIM' or 'Add Data Plan'. You can also visit our website, southesim.com, where we have a comprehensive list of all compatible devices to help you out.
Yes, absolutely! While St. Barths is small, its charming roads can be quite winding and signs are often minimal. Relying on your SouthESIM for real-time GPS navigation with apps like Google Maps or Waze is incredibly helpful. It ensures you can confidently find your way to hidden beaches like Saline or chic boutiques in Gustavia, making your island exploration smooth and stress-free.
You'll be pleased to know that your SouthESIM generally provides strong signal even at the serene and somewhat secluded Colombier Beach in St. Barths. Despite its remote feel, accessible by a hike or boat, you should be able to share those stunning photos of crystal-clear waters, swimming turtles, and luxury yachts. It's perfect for staying connected while enjoying this beautiful, tranquil spot.
You bet! SouthESIM offers robust coverage at St. Jean Beach in St. Barths, making it super easy to capture and instantly share those thrilling low-altitude plane landings at Gustaf III Airport. Whether you're uploading a quick video or posting a stunning photo to your social media, your connection will be reliable. So, get ready to make your friends jealous with real-time updates of your unique beach experience!
When you're exploring the wilder side of St. Barths, like the scenic areas around Grand Fond and Toiny, SouthESIM generally provides good signal along the main coastal roads. However, if you venture off onto the more secluded, rocky hiking trails or hidden coves, the connection might become a bit spotty. We recommend downloading offline maps or content before heading out to those truly off-the-beaten-path spots, just in case!
